New Federal Standards for Arsenic in Water


Homeowners in New England, where there are about 2.3 million private wells, should be aware that as of January 23, 2006, the EPA has greatly reduced the allowable amount of arsenic that can be present in drinking water, in order for it to be considered safe or "potable," from 50 parts per million to 10 parts per million (Maximum Contaminant Level = 0.010ppm).

It is estimated that up to 15% of all private wells in New Hampshire may not meet this standard.

Though the regulation was promulgated in January 2001, it did not take effect until today. If you purchased your home during the last several years, and would like to retest your water to ensure that it complies with the new standards, you can find a list of Massachusetts DEP-certified labs online.

If you rely on well water and are considering selling your home, it would be advisable to investigate the arsenic level now, and take remedial action, if necessary, for your protection and to forestall problems once your home goes under agreement.
